MARSHALLTOWN, IOWA (June 2, 2003)– Emerson Process Management has introduced the new Fisher® Design D4 control valve, a compact, rugged Globe valve designed for high-pressure throttling applications in the oil and gas production industry. The Design D4 valve is a contemporary replacement for the Fisher D body and Type 357 oilfield valves.
The Design D4 valve is available with pressure ratings to ANSI Class 1500 in 1″ and 2″ sizes, and has flanged or screwed end connections. With its ENVIRO-SEAL® packing technology, the D4 valve offers a long stem seal life. Rugged construction details like heavy-duty valve plug guiding and optional ST (super-tough) Carbide™ trim provide a long service life. Fisher ST Carbide trim is designed specifically for severe service applications. Two additional trim options allow users to configure the D4 for sweet or sour applications.
Easy-maintenance features include quick-change and hammer nut bonnet/body joint. A patented hammer union serves as a safety feature.
The Design D4 valve is Emerson’s newest addition to the family of Fisher oil and gas control equipment. Emerson meets the needs of those involved in the oil and gas industry with three recent Fisher product introductions: the Design D4 valve for throttling control applications; the Type D2 FloPro™ control valve for on-off dump applications; and the Type L2 liquid level controller for high pressure liquid level applications.
